[问题] 请问一个数学常识。

[spsun1]

as I suggested, just run spss to see what are the differences between the two regressions.
I do not have SPSS and never use it. It you are not sure, send me the results. I will go through with you. spsun1@yahoo.com

Thank you so much, spsun1!!

I think that I have kind of figured out what it means. I think in this case, there will be only two models, rather than three of them if we ENTER the variables one by one. while, as you can see, it's part of the the other message that I have posted, what the question concerns is to analyze Model 1 with only one variable, and Model 2 with 3 variable. I think it should be the case. Do you agree?

Thanks for your help and offer, thanks a lot!

绣球我是接了，但太重，没接住，还差点砸着我。 仔细一瞧，绣球上写着：名花有主，请勿夺人所爱。

原来MM是在取笑我。
我已是夜不能寐，食不甘味。人生的痛苦莫过如此。

Yes. you are correct. As I said, just run them and review the results, you will find out what are the differences between them. On the second question, we could say, prediction beyond the actual data range will not be reliable.

一声叹息...

You think so? But there are only 28 cases in the sample.

Will that be reliable to make the statement below?
